Texas Man Fights Charge of Warning Drivers About Speed Trap

Laws in New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia and Florida allow headlight flashing, while other states, such as Arizona and Alaska, forbid it. In Washington, drivers may be fined $124 for flashing their high beams within 400 feet of another vehicle for any reason.

Last July, a Missouri man sued the city after receiving a ticket for violating a local law against flashing lights on certain kinds of vehicles, while in May 2012, a Florida judge ruled that a man arrested for flashing his headlights was exercising his freedom of speech under the First Amendment.
